Karl Friston
British neuroscientist who developed free-energy principle for brain function.
Most quoted
"The free energy principle is a variational principle for adaptive systems. It says that any self-organizing system that is at equilibrium with its environment must minimize its free energy."
— from Scholarpedia, 2010
"The free energy principle is a mathematical expression of the idea that living systems are constantly trying to minimize their surprise."
— from Scholarpedia, 2010
"The free energy principle is a theory of how the brain maintains its internal states in the face of a constantly changing environment."
— from Scholarpedia, 2010
All quotes by Karl Friston (103)
Self-organization arises from the imperative to resist entropy.
Bayesian brain hypothesis: all cognition is approximate inference.
Action is inference on the path to least surprise.
The hierarchy of the brain mirrors the hierarchy of the world.
Free energy is the bridge between thermodynamics and psychology.
Learning is the optimization of internal models against reality.
The self is a process, not a substance; inferred at every moment.
In the realm of inference, doubt is the fuel of discovery.
Cognitive architectures are built on layers of probabilistic predictions.
Surprise is the spark that ignites adaptation.
The mind's eye sees not light, but likelihoods.
Active inference explains why we move: to confirm our priors.
Variational methods approximate the unapproximable dance of life.
The brain is a prediction engine, perpetually forecasting its fate.
In uncertainty, the wise brain weighs evidence with precision.
Generative models are the poems of the neural architecture.
Life's purpose? To minimize the free energy of existence.
Inference engines drive the evolution of intelligence.
The boundary of the self is a blanket of Markovian fate.
Every thought is a bet on the hidden states of the world.
